The self-stowing Ultralight Travel Daypack is so amazingly practical that it will become one of your travel essentials. Packed it appears as a compact pouch about the size of your cell phone and it opens into a feature rich travel daypack. When stuffed back into the side storage pouch, your daypack is ready for action in your car, your purse, your backpack or your bike saddlebag. Daypacking in bliss has never been so convenient.
